FILING MACHINE.

AppIication filed January 16,1924. Serial No. 686,532.

To all whom t may concern: i i fi Be it known that I, RICHARD I-I. FREITAG, a citizen of the United States, and a resident of Akron, county of Summit, State. of4

lthey can bevreadily called intol use without changing or adjusting the machine.

With the improved machine herein shown a `gang of files is mounted within the machine, each with its own reeiprocable carrier, and in operative relation to all of the carriers is a common actuating member. i Means areprovided to throw any one of said files,

.Vor more than one ile at a time, into connec tion with the actuating member. .The files which 'are not in use are located below the `work table so not to interfere with the operation of the remaining files. i

The machine herein shown is suitable for all types ofwork Vof this general nature and is extremely useful and practical. As far as known to nie, it is the first practical inachine of this type and the description and claims herein are, therefore, entitled to a liberal scope in defining the invention.

I-n the drawings: y Figure 1 is a vertical section through the machine;

Figure 2 is a 'section at right angles to Figure 1, the section lines 2--2 on Figure 1 land 1-1 on Figure 2 indicate the points at which the sections are taken, respectively;

lFigure Bis a sectionon the line 3M3 of Figure 1;

y Figure 4 is a plan view of the work table.

In the drawings, 1 represents a work table -which'is horizontal in the present form of the invention, but which may be arranged at lanysuitableangle. The table is supported upon standards 2 which are tied togetliei'` at their lower ends, by a transverse `shaft 3 arranged in lugs 4 atthe basey of the standards. y 4

The table 1 is provided with a series of apertures 5, which, in the present form of the invention, are arranged in a circle. De-

pending from the under side of the table and located atthe center of the circle is a guide post 6, which is provided with a feather 7, and on the guide post is a reciprocating sleeve 8. At a point on the sleeve is arranged a sliderblock 9 which is engaged by a crank-pin 10 on the face of a disk 11 that if:

is carried by a. rotating shaft 12. The shaft 12 is supported `within a bearing plate 13 which is bolted to the under side of the table by brackets 16. rlhe shaft is arranged to be rotatedby a motor 14 also secured tothe under side of the table, the motor shaft and the shaft 12 having interconnecting worin or spiral gearing indicated bythe numeral 15. The motor shaft 17 is supported at its i outer end by a bracket 18. The sleeve 8, which has been described, with its operating parts, is the common actuating member referred to inthe opening portion ofthe spec-ilication.

`The plate 13 is provided with a centrally locatedfopening 20 to accommodate the part 8 and is formed with a plurality of integral bearing sleeves 21 which are arranged in circular relation to register .with the openings 5 in the table. Each sleeve has slidably mounted therein a tool carrier 22 in. the up- .per Aend of which is a collet 28 in which is secured the tool 24 in positionto be received inthe .opening 5. herein, the tools are' files and each carrier is aiiangedto support a diiferentfile either in shape or grade as may be needed foi" the particular work for which the machine is In the machinershown designed. Except for the character of the iile, the tool carriers are of similar design and a description of one will suflice for the lot. i

The carrier 22 is in the forni of a vertical barrelhaving a. keyway 24"*` engaging with? The sleeveeXtends below the plate 13 slightly and at its lower end carries arplate 25 which is 4held in position by the bolt 26 which operatesthe collet. A spring 27 surrounds the barrel between the lower end of y the sleeve and the plate.

, At one side of the bearing 21 is a second Y bearingv 28 in which is slidably mounted a plunger29 working against a.` spring 30. The plungerpcarries `upon its lower end*` a rocking arin 31, one end of which projects* Y beneath the v tool carrier and the other end of which projects beneath a flange 32 on the lower end of the actuating member 8. 'Ihe plunger 29 is arranged to be. elevated to bring its tile into operative relation to the actuating member and to project it above the table. In Figure 2, the right hand tile is elevated in operative position, while the left hand iile is depressed or in inactive position. Each plunger 29 carries at its lower end a bearing block 33 provided with a pin 84 to which is connected a lever 35 pivoted to-a pedal 36 which is rotatably mounted on the shaft 3. Then an appropriate pedal is depressed the link 35 is actuated to raise its plunger 29, elevating the file and bringing it in position to be actuated by the reciprocating sleeve, which, while the machine is in operation, is in constant motion. As each iile is connected to a single treadle,` the operator merely selects the tile he desires to use, presses the treadle and the tile is presented above the table and in rapid reciprocation.v Each treadle is provided with a stop 37 designed to limit the downward movement of the plunger and with an adjustable pin 38 which strikes a cross bar 39 on the base of the machine. The pin 38 is so adjusted that when the treadle is depressed the link is thrown slightly past center so that the parts reina-in in elevated position.

It is believed that the operation of the parts will be understood from the descrip- 35 tion which has been given and the utility of the machine will be apparent. The arrangement shown provides a quickly operated means ior performing many classes of tiling work which are required in a. single ljob or in several jobs. One or more liles can be placed in operation as desired. I-Ieretotore, single -iling machines have been on the market, but I do not know of any multiple tiling machine which has been avail- `able to the workman, or one which em- Yalthough its design is for that especial purpose.

That is claimed is:

1. A machine of the character described comprising a plurality of reciprocating carriers, a tool in each carrier, a common actuating member therefor adapted to be operated continuously but normally disconnected from the tool carrier, and means to place any one of said carriers in operative relation to the actuating member.

2. A machine of the character described comprising a work table, a plurality of tools supported below said work table, an actuating member for reciprocating one or more of said tools, and means to project a tool above the table and simultaneously place it in operative relation to the actuating' member.

8. A machine of the character described comprising a work table, a plurality of tools supported below said work table, a single actuating member normally disconnected from the tools, and means to place a tool in position to be actuated by the member above the table.

il.
